摘要： Apparatus for separating oil from crankcase ventilation gases of an internal combustion engine having at least two oil separators in the form of cyclones connected in parallel and traversed by the crankcase ventilation gases. The apparatus is equipped with a control valve that divides the volumetric flow of the crankcase ventilation gases into at least two subflows, depending on the magnitude of the volumetric flow, and conducts the subflows to the at least two oil separators. A control piston releases or blocks access of the gases to additional cyclones depending on the dynamic pressure of the crankcase gas.

摘要： A microprocessor is used to control the temperature of a laser emitter and thereby regulate the wavelength of optical signals from the laser. A serial interface in the microprocessor provides input and output lines to a host device, and temperature lookup tables are stored in nonvolatile memory. Control logic processes information stored in the memory as well as information on operating conditions of the laser emitter to precisely control the temperature of the laser emitter. A thermo-electric cooler adjusts the temperature of the laser emitter.

摘要： A method for compensating for wavelength drift in a fiber-optic laser transmitter includes 1) controlling a temperature within the optoelectronic assembly at a defined level; 2) driving the optoelectronic assembly to emit light, wherein the emitted light has a wavelength that is within a channel of operation, the channel of operation including a range of wavelengths centered around a channel center wavelength; 3) accessing from memory within the optoelectronic assembly a control value associated with the temperature of the optoelectronic assembly at defined points within an operational lifetime of the optoelectronic assembly; and 4) recalculating the defined level by reference to the control value, whereby a wavelength of the optoelectronic assembly is maintained within the channel of operation despite an expected drift of wavelength.

摘要： One example of a method for operating a transceiver includes selecting a first operating wavelength from a set of operating wavelengths. Next, a first control value is accessed that corresponds to the first operating wavelength. The first control value also corresponds to a first operating temperature of the transceiver, and the first operating temperature resides within a range of about 30° C. to about 50° C. Finally, the transceiver is operated substantially at the first operating temperature.

摘要： A system and method for testing the jitter tolerance and signal attenuation tolerance of an optoelectronic device is disclosed. The system includes a generation circuit, delay circuit and comparison circuitry. A first sequence of bits is generated, delayed, and sent to the optoelectronic device. The optoelectronic device receives the bits and retransmits them as a second sequence to the comparison circuitry, which compares the two bit sequences to determine a bit error rate. The bit error rate is then used to determine the jitter tolerance and, in an alternate embodiment, the signal attenuation tolerance of the optoelectronic device being tested.

摘要： Exemplary embodiments of the present invention selectively adapt the pad architecture on bi-directional opto-electronic transceiver modules to connect to legacy unidirectional ports, panels and the like. This allows the bi-directional module to function correctly when connected to either a unidirectional or a bi-directional port. Conversely, exemplary embodiments also selectively adapt the pad architecture on bi-directional patch panels or ports to connect to legacy unidirectional optoelectronic transceiver modules. This allows the port to function correctly when either a bi-directional or a unidirectional transceiver is connected to it.

摘要： A method of protecting a glass substrate, especially a display glass or a hard disk blank made from a glass or a glass-ceramic, from unacceptable surface damage and scratches, often leading to glass breakage, during processing and transport, is described. This protective method includes applying a removable protective coating made of at least one polymer layer, or at least one polyvinyl alcohol layer, to the glass substrates by spraying or rolling the polyvinyl alcohol or a polymer solution of the polymer to be applied in a polar organic solvent, onto the glass substrate, or dipping the substrate into it. Then when the substrate is ready for its end use, the protective coating is removed by washing in water or polar organic solution so that a residue does not remain on it. The glass substrates, protected in this manner have outstanding surface quality and improved hard disk blanks can be economically produced from them.
